Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

My great concern is not whether you have failed, but whether you are content with your failure.

Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.

Admitting failure is quite cleansing, but never - pleasurable.

Success is never final, failure is never fatal. It's courage that counts.

Once you start a working on something, don't be afraid of failure and don't abandon it. People who work sincerely are the happiest.

Failure seldom stops you. What stops you is the fear of failure.

Failure is not our only punishment for laziness there is also the success of others.

They who have conquered doubt and fear have conquered failure.

We may be personally defeated, but our principles never!
